of the wing-quills marked with rufous or chestnut 

 colour* 



The Ashy-black Tyrant inhabits the Mendoza

 bird rises up a few feet into the air. During this 

 performance the white bands on the wings are dis- 

 played conspicuously and a humming sound is

 which it closely resembles, is a summer visitor to 

 Patagonia, where it makes its appearance in October. 

 The plumage is intense black, with the inner webs 

 of the remiges at their base white, but the wing- 

 band, which is over an inch in breadth, shows only
